The percentage of people who said these and other traditionally
taboo issues are morally acceptable are at record highs, Gallup
notes.

Below is a chart that displays the survey results, with an
asterisk denoting the issues for which moral acceptability is at
or near a record high:

Some issues, such as affairs and cloning humans, are still
considered unacceptable, but even those areas are gaining
traction and have a higher rate of moral acceptability than in
past years.

Surprisingly, barely half of respondents said gay or lesbian
relations were morally acceptable, but that rate is still a
record high for the issue.

The difference in these rates over the past few years isn't
drastic —
2010 numbers are fairly similar — but some issues that were
contentious among the American people about 10 years ago have
become largely acceptable today.

Americans have largely come to accept divorce, premarital sex,
and homosexual relations
since 2001, when Gallup first conducted a moral acceptability
poll.

In 2001, 59% of respondents considered divorce morally
acceptable, 40% said homosexual relations were OK, and 53%
approved of premarital sex. Today, those rates are at least 10
percentage points higher on each issue.
